FEP Extrusion Grade
Detail Information
FEP Resin for Extrusion
FEP is the copolymer of tetrafluoroethylene (TFE) and hexafluoropropylene (HFP). It has excellent thermo-stability, outstanding chemical inertness, lowfriction coefficient, distinctive air aging resistance, vapor penetrating resistance, non-inflammability and superior electrical insulation.
FEP extrusion grade is mainly used in extruding insulation layers and jackets for conducting wire and cable. It’s also widely used in the production of pipe, tube, film and etc.
